High-flux thin-film nanocomposite reverse osmosis membrane for desalination

Use of nanofiber composites to create a higher filtration rate in reverse osmosis for energy efficient separation Background: Reverse osmosis (RO) is one of the most energy efficient separation technologies to remove salt ions from brackish water or seawater. Conventional RO membranes possess a thin film composite (TFC) structure, containing an ultra-thin barrier layer. This layer can be used as a filter. However, nanofillers may be incorporated into the polyamide barrier layer to improve either the permeability or separation efficiency when separating materials. Technology Overview: Using a nanocomposite barrier layer containing cellulose nanofibers and a polyamide matrix, traditional ultrafiltration (UF) substrates have demonstrated two RO applications: low pressure desalination of brackish water and high pressure desalination of seawater. Some embodiments include having cross-sectional composite fibers with such as methyl, ethyl, and butyl. In other functions, nanofibers may be physically incorporated in the barrier layer of a membrane by interfacial polymerization. Advantages: -More efficient
